took me be surprised, it would be interesting to see if this fits on any belt driven FI.. perfect for turbo for sure..

to me, Nick

Small kit is:

Camshaft (yes you have to, sorry)
LT4 Pump conversion kit
Set of 8 DI injectors (30% over LT4)
$4995 retail

Small kit is ready to go as well, makes 920whp on E42 with F1A-94.
To be tested with turbos, should do 1000whp on E30.

Big Kit:
belt driven 2nd DI pump
supports 1200rwhp

You will need low side upgrade as well for each level.

I am working on a kit, best know as of now is FORE.

------------------------------------------------------------------------

One part of me wants to invest in 8 intake manifold mounted injectors and skip the limits of the DI system. But on the other hand, i really like only have to datalog one computer and look/edit fueling in one place..

i guess i'm at a fork in the road lol

[TEEZYSS]

Just some info

I messed with ECOBOOST's awhile back and Xtreme DI ending up offering 2 high pressure fuel pumps a 30% and 60%. Neither ended up doing very well when it came to longevity. They had overheating problems and didn't seem to supply the fuel demand they claimed it would support.

Best route for DI and big power IMO is 42AUTOSPORT secondary fuel system.

Now if gm would make a retrofit. Zr1 ECU twin inject available that would be money

I only log with hp tuners and I typically only tune the fuel on one ecm Depending on weather I am doing part throttle stuff or wot stuff. Dialing in the wot fueling with a stand alone using a maf table is ridiculously easy.

Staying all DI and having just the one ecm would be nice in some ways but I love all the extra features that come with a stand beside ecm.

Besides aux injector control I am using mine for aux fuel pump control, nitrous control(progressive, window switch, wot switch, boost builder, heater control and pressure monitoring), boost control(speed based, closed loop boost targeting, 2 table switching on the fly), tablet gauges that are only limited by your imagination, coil cut off when wot and lean.

This is just what I am using on my car right now. There is a pile of additional features.

Are the injectors included with the kit?? It says they are required on Katechs website and list for $3480. So are we at $4495 or $7975 plus cam

I don't see it fitting with a Procharger. Looks like the bracket and pump are mounted where the head unit goes.

That is a wicked setup and would work perfectly for my future 900 rwhp setup

Wish GM did what Ford did with their dual fuel system. I have my build plan and told myself when it runs low on fuel I am done with adding power. The cost is just unreal.

I do like the features and I wanna join the bandwagon.. but lets be honest.. the average joe doesn't need all this stuff. only someone with a hot rod needle in their vein does haha

i want the new zr1 pcm to be retrofitted to my car to control the additional fueling.
